Sea Wraith - The Meranda Haley Series, #2

Meranda, still working to get her private investigator sea legs back, takes a case from an elite businessman who promises a payout that will keep her Agency afloat. But when the client won't tell her anything about himself, or even what he's missing, Meranda entrusts her reputation, and the fate of the entire Agency, on the expertise of a mysterious stranger. The closer they work together, the more Meranda realizes that this stranger has secrets to hide--secrets that involve her.
As betrayals spiral and her new partner's own ghosts come to call, Meranda must rely on her own skills to find a solution to both problems before time runs out. Except now there's more at stake than her father's Agency. Now, the stranger's secrets endanger them all.
